Top Software Testing Companies in Singapore

Fundamental principles of the top software testing companies in Singapore

If you take software testing seriously, it is worth getting acquainted with its main principles in order to know the process inside out.

Testing proves bug presence, not bug absence

Testing is executed to detect bugs and fix them before a product is deployed to production. In such a way, we can be sure that an application works properly. Still, the best software testing services in Singapore do not confirm that an application is completely bug-free. It helps significantly decrease the number of bugs in software, but it cannot prove that all bugs have been caught. 

There can be still bugs in software that can reveal themselves only under some particular conditions. This principle should always be considered, and corresponding actions should be taken to manage client expectations. In these terms, it is also useful to monitor a system after release and foresee potential risks in advance.

Exhaustive testing is not feasible

We all wish it could be possible to test software exhaustively. Moreover, top software testing companies in Singapore do their best to achieve this aim. Still, the reality is cruel. It is just absolutely not feasible to cover with tests all possible combinations and conduct testing under all possible conditions. Such exhausting testing would require a lot of resources, time, and money. This is absolutely unacceptable. 

Moreover, it does not make sense. Efficient test planning, proper test case prioritization, and correct risk assessment can help you cover with tests the most important app functions and reach an acceptable level of product quality, without checking every single code line.

The earlier testing is started the better

This is indeed a golden rule of software testing companies in Singapore. Following this principle, you can save a vast amount of money and time. In the perfect scenario, a QA team should get to work at the stage of requirements analysis, i.e. before even a single line of code has been written by developers. 

The thing is that requirements may contain bugs as well and it is much easier and cheaper to correct mistakes in requirements than to rewrite code in order to fix bugs in the developed software with a risk to affect another functionality and miss deadlines.

Defects tend to cluster

According to this principle, most bugs are located in particular software modules, i.e. the Pareto principle is applicable in this case which means that eighty percent of bugs are contained in twenty percent of the source code. Taking into account such bug density, it is reasonable to focus on these critical software areas, especially when it comes to testing large-scale and sophisticated systems that contain more dependencies. So if a bug has been found in a certain module, there is a high chance to find there many more defects.

Bear in mind the pesticide paradox

In agriculture, when the same pesticide is used on an ongoing basis, injurious insects eventually get used to it and resist it. As a result, this pesticide becomes ineffective. The same happens with test cases. If software testing companies in Singapore execute the same test cases on an ongoing basis, they finally fail to detect new bugs. In this context, it is essential to regularly review and modify existing test cases and create new ones.

Testing depends on the context

The context plays a significant role in software testing defining test approaches and methods that should be used to reach the set goals. There is a strong dependency between a type of application under testing and chosen testing approaches. For example, social network testing radically differs from bank system testing.

100% bug-free software is an illusion

You may execute an endless number of tests and find a vast number of bugs, but it cannot guarantee that your application is completely bug-free. Even if all ins and outs of software have been thoroughly checked and all revealed bugs have been fixed, your software can be unusable as users’ expectations and needs are not met. This can indicate a gap in the business requirements.

So software testing seems to be easy just at first glimpse. In reality, it is a sophisticated process that required a lot of resources and skills as a great number of things must be considered to provide high software quality. So choose the top software testing companies in Singapore to hit the market with an excellent product.
